EGG-TESTE R.

SPECIFICATION forming part Of Letters Patent NO. 242,150, dated May 31, 1881.

' Application filed January 27, 1880.

To all whom tt may concern:

Be it known that I, HOLLAND G. PIERCE, of Berlin, Wisconsin, have invented certain new and useful Improvements in Egg-Testers; and I do hereby declare the following to be a full, clear, and exact description of theinvention, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings and the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in egg-testers.

Heretoforeit has been common to construct egg-testers with but one opening for the passage of the rays of light from the flame to the egg, which opening has been arranged between the flame and the observer. Egg-testers were formed thus because it was thought necessary to the proper examination of the egg that it be placed in the line of vision between the flame and the eye of the observer, in which case it is impossible to examine more than one egg at a time.

It has been demonstrated that eggs can be more accurately tested when the observation is taken from one side, while the rays of light are thrown through them on a line at right angles to the line of vision of the observer. When thus arranged it is obvious that eggs may be examined equally well upon both sides of the flame at the same time. It is also ob- .vious that by this arrangement the observer avoids the direct contact of the rays of light upon his eyes while the eggs are removed from the opening.

,The object, therefore, of my invention is to provide a device by which the rays of light may be thrown simultaneously toward the right and left hand of the observer, whereby two eggs may be examined atthe same time, while the eyes of the observer are at all times shielded from the direct rays of light.

My invention is further explained by refer- 4 5 ence to the accompanying drawings, of which Figure 1 represents a front view. Fig. 2 represents a vertical section.

A is a cylindrically-shaped tube, formed of metal or any opaque material which will shield the eyes from the direct rays of light. The respective sides of the tube A are provided with tubes 1) b, oflike material, which are connected therewith by joints or seams G (J, and extend toward the rightand left atright 5 angles thereto, as shown. The lower end of tube A is provided with slot E, by which it is adapted to be used with and upon an ordinary lamp. The tubes 1) b are respectively made conical in shape, converging slightly toward their outward ends.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

As a new article of manufacture, the eggtester herein described, consisting in the combination of the vertical tube A, provided with slots E E, and two conically-shaped horizontally-arranged tubes, 1) b, adapted to permit the rays of light from within to pass out toward the right and left, whereby two eggs may be tested at the same time, while the eyes of the operator are shielded from the direct rays of light, substantially as set forth.

In testimony thatI claim the foregoingI 7 have aftixed my signaturein the presence of two witnesses.
